In many cases, it is very difficult to visualise the difference between sensor sizing just by reading through technical specs. The visual below might offer you a much better sense of the sensor sizing in the E-M5 III and E-P3.

As you have seen, the two cameras have the same sensor dimensions albeit not the same megapixels. You should count on the Olympus E-M5 III to resolve greater detail as a result of its extra 8MP. Higher resolution can also make it easier to crop shots a bit more aggressively. The more recent E-M5 III will have an advantage when it comes to sensor tech.
